Chrome or Chromium ores can be high grade, in which the chromite typically contains above 46% chromium oxide, or low grade, which is below 40% chromium oxide. The concentration of chromium is principally achieved by gravity separation, which utilises the differences in specific gravity to achieve separation. The techniques used include:

  • Spirals – can separate more than two components, making them effective in producing a cleaner concentrate
  • Jigging – especially effective when the density difference between the chromite and the gangue is quite large, enabling a clean separation.
  • Wet tabling – best for finer material, and cleaning duties

Naturally, each ore body acts differently and at METS we have the experience and expertise to determine an optimal process route for your ore body, depending on the mineral associations within the chromite ore.
